In the treatment of patients with Parkinson's disease, apomorphine has an established place as a back-up therapy if other antiparkinsonian drugs, such as levodopa and oral dopamine agonists, have not controlled the existing response fluctuations. Apomorphine is a synthetic derivative of morphine, with a totally distinct pharmacological profile. It is a very(More)
OBJECTIVE To identify determinants for the discontinuation of non-ergoline dopamine agonist (DA) treatment in patients with Parkinson’s disease (PD) and to identify genetic determinants in genes encoding dopamine receptor (DR)D2 and DRD3 in a exploratory analysis. METHODS Patients included were first-time users of the non-ergoline DA ropinirole or(More)
BACKGROUND Since bacteria embedded in biofilms are far more difficult to eradicate than planktonic infections, it would be useful to know whether certain Staphylococcus aureus lineages are especially involved in strong biofilm formation. For this reason, in vitro biofilm formation of 228 clinical S. aureus isolates of distinct clonal lineages was(More)
INTRODUCTION Dysfunction of brain dopamine systems is involved in various neuropsychiatric disorders. Challenge studies with dopamine receptor agonists have been performed to assess dopamine receptor functioning, classically using the release of growth hormone (GH) from the hindbrain as primary outcome measure. The objective of the current study was to(More)
BACKGROUND Sialorrhea affects approximately 75% of patients with Parkinson disease (PD). Sialorrhea is often treated with anticholinergics, but central side effects limit their usefulness. Glycopyrrolate (glycopyrronium bromide) is an anticholinergic drug with a quaternary ammonium structure not able to cross the blood-brain barrier in considerable amounts.(More)
In this study, we measured the relationship between plasma and cerebrospinal fluid (CSF) apomorphine levels and their clinical effects in two patients with Parkinson's disease (PD). After subcutaneous injection of apomorphine, serial samples of plasma and lumbal CSF were taken and serial scoring of motor responses was done using the Webster Rating Scale.(More)
Five patients with idiopathic Parkinson's disease with severe response fluctuations were selected for a randomized double-blind placebo-controlled study, concerning the clinical effects of subcutaneous apomorphine and its assessment in 'off'-periods. The study was designed as five n = 1 studies, in which every patient was his own control. The effect of(More)
BACKGROUND Potential drug-drug interactions (PDDIs) in patients with cancer are common, but have not previously been quantified for oral anticancer treatment. We assessed the prevalence and seriousness of potential PDDIs among ambulatory cancer patients on oral anticancer treatment. METHODS A search was conducted in a computer-based medication(More)
BACKGROUND Drug-induced pulmonary toxicity is a serious and expanding problem with often unknown aetiology. Many drugs are metabolized by cytochrome P450 (CYP) enzymes. OBJECTIVE To establish whether allelic variation in CYP polymorphic genes contributes to variability in drug response and unexpected toxicity. METHODS A case-control study was conducted.(More)
To date, the interchangeability of generic drugs has only been investigated for a limited number of medicines. The objective of this study was to investigate generic-generic drug interchangeability in a large subset of generic formulations in order to cover a broad spectrum of drugs. Orally administered drugs for investigation in this study were selected(More)
